Let me requote myself: I Still Believe In My Damn Therory!!! I see your point but....I still think that Killing yourself and having a second third and fourth in command ready to leave the ship, abandon it and to be the only sane person aboard and end up dying That's the stupid part!!!
But the problem with your theory is that it actually took the physical conflict to snap Spock out of it. You have no idea how long it may have taken with Kirk just taunting him from the other side of a force field.
